Admin-level stored XSS via unescaped application ID

Published Jun 13, 2022 · Updated Jan 31, 2025

Stored XSS in Mitsol Social Post Feed before 1.11 allows remote authenticated users to inject scripts through application ID settings. The plugin stores application ID values without sufficient sanitization and emits them into HTML attributes without context-appropriate escaping. Administrator access is required, and injected JavaScript runs when another user visits the affected page; exposure is limited to multisite installations or sites where unfiltered_html is disabled.
